摘要
The procedure for the construction of underground transport infrastructures, comprises the steps of: excavating an underground transport tunnel (1, 2) comprising a first pipe (1) and a second pipe (2) substantially parallel to one another; making a bypass tunnel (4) connecting the first pipe (1) and the second pipe (2) which comprises the sub-steps of: - introducing a launching chamber (5) along the first pipe (1) up to a first predefined position (PI) chosen along the longitudinal direction (Dl) of the first pipe (1), the launching chamber (5) being able to launch a tunnel boring machine (6); introducing an arrival chamber (7) along the second pipe (2) up to a second predefined position chosen along the longitudinal direction (D2) of the second pipe (2), the arrival chamber (7) being able to receive the tunnel boring machine (6); excavating the bypass tunnel (4) making the tunnel boring machine (6) move forward from the launching chamber (5) to the arrival chamber (7) along a direction transversal (T) to the first pipe (1) and to the second pipe (2).
